High-Grade Nitinol Shape Memory Wire Material

Crafted from premium nickel titanium alloy—widely recognized as Nitinol—this wire offers two outstanding advantages:

Unique Functional Properties of Nitinol Wire:
This advanced wire exhibits two remarkable behaviors. The Shape Memory Effect allows it to return to a pre-defined shape when exposed to heat, enabling precise and repeatable transformations. At the same time, its Superelasticity lets the wire bend or stretch extensively under stress and then instantly recover its original form without any permanent distortion. These dual characteristics make Nitinol exceptionally versatile for high-performance, space-constrained applications.

These properties solve complex engineering problems in compact, efficient ways.

Durable Black Oxide Coating on Nitinol Wire

The wire’s surface is treated with a full-coverage black oxide finish that is bonded to the Nitinol for maximum durability.

• Reduces reflection for visual or optical use

• Offers excellent corrosion resistance

• Resists scratches, wear, and harsh environments

• Maintains its appearance without chipping or peeling
